With everything as a note, how was it so performant? How did it scale so well?

It was basically NoSQL before NoSQL.

Each note was just a record, but with no schema. Schemas were imposed at the UI layer by forms and at indexing time by views.



Baffling to see this, in every place I've worked at that used Lotus Notes, it was an absolute dog on the system. Clunky, slow, and ground everything else to a halt. And this was the case even on a relatively modern laptop in 2019. Not what I'd call performant at all!

Notes was simple enough to allow folks with no computer science background or even sympathy for the machine to build teetering, badly-performing things.

However, even with a mind towards efficiency and minimalism, performance at roughly hundreds of thousands of documents was extremely elusive.


It wasn't performant, and it didn't scale. I was in a Notes shop in the mid-nineties and it was dog slow for practically everything in a perhaps fifty person company.


It’s like they worked at my last workplace


Ritalin (methylphenidate) is a central nervous system stimulant used for ADHD and narcolepsy, but it is not an amphetamine based medication, unlike Adderall. While both increase dopamine and norepinephrine, Ritalin acts as a reuptake inhibitor rather than a stimulant that directly releases these neurotransmitters like amphetamines do.

Adderall saved my life. YMMV


Is there any actual difference between preventing reuptake and directly releasing them?


Almost certainly, this is biology, after all.


I would love to use RSS to disseminate updates I’m working on, especially to my family. But my family wouldn’t know what RSS was, let alone use a reader. Are there ways my family could already be using RSS and not know? I don’t want to try to get them to install yet another app or use another service because the friction will prevent them from doing it.


What about email?

Email is a cousin to RSS - everyone has their email feed.

Senders push to an email inbox, rather than readers pulling feeds into an inbox.


This is very interesting to me because a plant this old might be cheaper to operate than a new plant, but might be like the space shuttle in that replacement parts aren’t readily available and thus expensive to custom manufacture.

If you were to step into the control room you’d see analog phones, tiny incandescent bulbs behind plastic covers… looks like a sci-fi set from the 60s.

The expensive part of a reactor isn’t really the reactor or tech itself, it’s the government regulation from the DOE and NRC.

I worked at Areva/Framatome/B&W and IIRC they still have the archival room where hundreds of 4 inch D ring binders held the original design docs that had to be submitted for approval.


> tiny incandescent bulbs behind plastic covers…

Not too disagree with the bulk of comment, but this sentence is not true. They're 90V neon indicator lamps, a technology that's really cool but also so inefficient that people rip it out and replace it.

Neat rabbit hole to do down.


Appreciate the correction.


We absolutely need rinse aid here, even with a water softener. But we make our own with ethanol and citric acid. For us works just as well as the pricey stuff and costs us…. A large bottom shelf bottle of vodka (sorry, don’t drink and don’t buy this enough to remember) and about $0.50 in citric acid will last me 6 months.


Yeah, I have very soft water. I tried using a liquid rinse aid when I switched from a name brand pod with a rinse aid to the cheap Kirkland pods. The rinse aid made things worse and I did end up with a residue on my glassware.

It’s cheap enough to try it and see if it helps but don’t feel obligated to use it if it doesn’t.


Say more! Are you just squirting lemon juice into the bottle? How much? How often are you refilling the rinse aid reservoir?


I ordered citric acid off of Amazon (it’s great at getting out hard water stains in bathrooms and toilets and helps keep my water softener going well (I add some to the salt tank), also can add some good kick to lemonade)

For every cup of vodka (40 or 60% can’t remember, but prolly 40. Though scientifically 60% would be better) I add 1 to 2 tsp of powdered citric acid. Takes a surprisingly long time to dissolve so you’ll get a quick workout shaking it. I’ve added blue food coloring before to make it more visible in the dispenser to see the level but it’s not necessary at all so I usually skip it.

I make it in a 1 liter bottle which will last a couple months. We have a Bosch dishwasher, refill it… every couple of weeks maybe? I’m not the only one filling it. We do 1-2 loads of dishes a day (4 kids who can’t ever seem to find the cup they JUST used. Probably a parenting problem)

I have no idea if that’s helpful. But I did just lookup a cost by fluid volume- I live in a state with high alcohol tax rates and my cost per fluid oz of my DIY rinse aid is around $0.19 (mostly from alcohol, per fluid oz of citric acid is less than one cent. ) for reference, the small bottle of Jet-dry is $0.58/flOz.


Active state, that’s a name I’ve not heard in a long time. A long time.


So you know him then?


Not sure I understand your point, but if it’s helpful, I’m blind, prefer to be called blind, but get tired of educating people on what “blind” actually means as it’s a spectrum and not a binary condition.

In my community we refer to non-blind people as “sighted” which I suppose is also a spectrum.

Blind is very descriptive, and in my opinion not derogatory. I’d rather it not be my primary differentiator or descriptor unless comparing me to virtually identical people who have full or near full vision. “The blind engineer on the team” is ok with me as it’s the fastest way to describe me if we’re all middle aged guys with beards. If I’m the only bearded guy on the team of middle aged engineers I’d prefer “the engineer with a beard”


> A fighter jet and a helicopter based off the aircraft carrier USS Nimitz both crashed into the South China Sea within 30 minutes of each other, the Navy’s Pacific Fleet said.

>The three crew members of the MH-60R Sea Hawk helicopter were rescued on Sunday afternoon, and the two aviators in the F/A-18F Super Hornet fighter jet ejected and were recovered safely, and all five “are safe and in stable condition,” the fleet said in a statement.

>The causes of the two crashes were under investigation, the statement said.

An expensive loss to be sure but no loss of life.


Though not exactly the image the USN wants to project of this is meant as a show of force


Its a loss of many days of taxpayers lives.


Are the planes recoverable?


They're definitely total write-offs.

Yes* most of the time. The purpose is the Pentagon doesn't want adversaries or anyone else getting their hands on classified gear or aircraft systems because it's basically flying around with a datacenter nowadays. If it's in deep water, NAVSEA may bust out FADOSS gear and make it a OJT exercise for junior recovery personnel.

In recent memory, the scorecard is:

- Truman (CVN-75): 1: JUL-22, 1: DEC-24 (friendly fire), 1: MAY-25, 1: APR-25

- Nimitz (CVN-68; decomm APR-26): 2: OCT-25

(Consider there are 9 additional carriers too.)

Nimitz does an average (mean) of 18.4 arrested landings a day over a span of 52 years.

Truman went 75000 landings (10-11 years) without a major mishap once upon a time™.

~7-8k fixed-wing landings per year per ship, roughly.


Even if nothing was damaged (like that's going to happen) after you fish them out of the drink you think they can be put back in service? Just look at the boosters on the Shuttle--the cost to refurbish them after their dip in the ocean was almost as much as buying new. Valuable in as much as it showed the problem that lead to Challenger, but they refused to look.


We're talking about the U.S. and its seemingly limitless military spending.

Even if they were recoverable, they would still order new ones.
